How to save water in the bathroom

Ways to reduce the bathroom water usage

Have you ever wondered how much water do you use during your daily bathroom activities?

It may actually come to a surprise to learn about the high amount of water that we use for bathing and showering.

We call it to wasted water because we may be able to achieve the same results while using less water

Let us show you what we are talking about and how you can reduce your bathroom water usage and conserve water.

Measure water usage

First you need to know how much water you are using and then you can decide if:

– Are  you are wasting water?

– Where you can start saving water?

You need to start by finding out your home’s water flow, this is how many litres of water per minute do your shower head or your water taps use. For that, you can just use a bucket and measure the time that it takes to get the bucket filled to the one litre mark. 

The time it takes to fill up the bucket to the one litre mark let’s you know how much the water flow is. For example, the tap delivers 1 litre of water every 5 seconds or the shower head delivers 9 litres per second.

For more information about how to measure the water flow rate, have a look to the video we have added below. Also, this site provides a very good overview and the difference between water flow and water pressure.

For measuring the toilet water usage, you will need to take the water meter readings before and after flushing the toilet. The readings will let you know how much water your toilet is using, for example, 10 litres per flush.

Again, for more information about how to read a water meter, have a look to the video we have added below.

And as example, in our case, this are our water flow rate results:

It is shocking to realize how much water it is being used in just a few seconds, specially while having a shower.

Know that you know how much water you are using per second or every time that you flush the toilet, the next step is to gather some additional information: 

– For how long and how often are you taking showers. Does everyone at home spend the same time under the shower?

– An approximation on how many times per day the toilets are flushed.

– An estimation on how long you are using the water taps during the day.

And with all the information you have collected, you can already estimate your water usage and water cost. 

In our case, for our household, this are our results:

After estimating how much water and money we are spending and where we are spending it, we got to know that our water fixtures are using a considerable amount of water in just a few seconds.

With that information, we started checking if it was possible to reduce the water flow through a cost effective solution.

Water reduction valve

After doing some research, we decided that installing an adjustable water flow valve it is an easy and economic way of reducing the amount of water we use while having showers.

With this valve we have managed to reduce the shower water flow from 1 liter every 5,5 seconds to 1 liter every 8,5 seconds without actually noticing any difference while having showers.

The advantage of the valve is that it is manually adjustable, so if some day we need to increase the water flow rate, we can do it without any effort. 

Or, if our small children are just playing with the water while enjoying their shower, we can decrease the water flow down to 1 liter every 10 seconds without them noticing any difference.

Additionally, the valve is discrete and unless you know it is there it is barely noticeable. 

For more details and specifications, clicking on the valve image below will direct you to the product in Amazon..

Another solution that popped up by just having a closer look was that we could adjust the sink water flow rate though the valves.

This way, we have adjusted the flow rate from 1 litre every 5 second to 1 litre every 9 second.

1 litre of water every 9 seconds for cleaning hands, face or washing the teeth it is more than enough.

Water saving tap aerator

Old faucet models run on average of around 15 liters of water per minute while a standard aerator can reduce the water usage to as little as 6 litters per minute

Water saving tap aerators can reduce the water consumption even further and due to their low cost and easy installation they are most definitely a water saving method to have in consideration.

We have installed a water saving tap aerator and the results speak by themselves

Water saving toilets

In our case, the toilet flushing didn’t present any water saving opportunity. Our house has a dual flushing toilet which is one of the most efficient solutions on the market.

Still, have in consideration that some very old toilet use considerable amounts of water, up to 15 litres per flush

If this is your case and you are thinking about investing into installing a new toilet, just take some readings, crunch some numbers and the result may help into deciding if the saving are worth the investment.

Ways to conserve water

Water conservation can be defined as the decision and the act of using less water

Water conservation both benefit you and the environment 

The act of saving and conserving water does benefit you because you will be paying less on your water bills. 

And it also does benefit the environment because conserving water prevents any unnecessary waste of natural resources.

Now, at individual level it may not look worth to try to save a few litres or gallons here or there. 

Still, every little counts and if hundreds or thousands of us do save a little every time, it will make an important contribution towards conserving our natural resources.

 

For example, if 9000 households would manage to save as little as 5 liters of water per day:

> Collectively, we would be saving over 16,000,000 liters of water per year!

> Collectively, assuming a cost of 2 euro per cubic meter of water, we would be saving nearly 33,000 euro per year!

It is clear that small water savings do really count when looking into the bigger picture.
